Governing bodies answer for the organization achieving its purpose ethically, effectively and responsibly and in keeping with what stakeholders expect. ISO 37000:2021, 4.1 breaks this down into five tasks: fixing and committing to the organization's purpose and values; deciding how it will generate value; directing and engaging with the strategy for doing so; keeping watch that the organization's performance and conduct match what the governing body expects; and being accountable for that performance and behaviour. An indicator is useful when it measures performance against the purpose, which is why indicators are conditions, quantitative or qualitative, that can be described, measured or calculated.
